Helm delete all releases

I'm trying find a way to delete all deployed releases in Helm.

It appears that Helm does not support deleting all releases, with --all or otherwise.

Would there be another way to delete all Helm releases in one command?

If you use xargs in the alpine container then you will get the following error;

xargs: unrecognized option: L

So, you can use the following command to delete all releases in a specific namespace for the helm v3.

helm uninstall -n <namespace> $(helm ls --short -n <namespace>)

To delete all releases in a particular namespace

helm ls  --short  -n <<namespace>> | xargs -L1 helm uninstall  -n <<namespace>>

To delete all Helm releases in Linux(in Helm v2.X) with a single command, you can use some good old bash. Just pipe the output of helm ls --short to xargs, and run helm delete for each release returned.

helm ls --all --short | xargs -L1 helm delete

Adding --purge will delete the charts as well, as per @Yeasin Ar Rahman's comment.

helm ls --all --short | xargs -L1 helm delete --purge

On Windows, you can delete all releases with this command, again, with --purge deleting the charts as well.

helm del $(helm ls --all --short) --purge

Update: As per @lucidyan comment, the --purge arg is not available in Helm v3.

There is a really good plugin for delete all helm releases from all namespaces (The previous plugin in this post doesn't work for me) . Install:

helm plugin install https://github.com/BarelElbaz/helm-delete-all

usage:

helm delete-all

you can provide more flags such as --deletePersistent for delete PVCs or skipping a specific namespace by --except-namespace

I regularly delete all releases in Helm too, so I thought it'd be useful to make a Helm plugin for it.

Install:

helm plugin install https://github.com/tedmiston/helm-delete-all-plugin --version 0.0.3

(You may be able to omit the --version x part on newer versions of Helm.)

Usage:

helm delete-all

helm delete $(helm ls --short)

Description:

helm ls --short gives a list of releases ids.

helm delete id1 id2 id3 deletes releases with ids: id1, id2, id3.

So combining them we get: helm delete $(helm ls --short)

For helm 3 you have to provide namespaces so there is an awk step before xargs :

helm ls -a --all-namespaces | awk 'NR > 1 { print "-n "$2, $1}' | xargs -L1 helm delete

This results in commands like:

helm delete -n my-namespace my-release

This worked for me in a powershell cmd window:

helm del $(helm ls --all --short) --purge
